Abstract

The invention provides an ozone aging testing case device, which has large content and high testing efficiency, can implement the test of multiple working pieces in each time under the precondition that ensures normal testing requirements, and comprises a testing case; a testing region and an air channel are arranged inside the testing case, the air channel and the testing region are communicated into a circulating system, a heater, an anemometer, a fan and an ozone generator are arranged inside the air channel, a testing shelf, an ozone concentration detector and a temperature sensor are arranged inside the testing region, the bottom of the testing shelf is connected with a drive and transmission structure, the fan and the anemometer are connected under electric control through an air flow speed controller, and the ozone concentration detector and the ozone generator are connected under electric control through an ozone concentration controller; the temperature sensor and the heater are connected under electric control through a temperature controlling device, and an output pipe of an oil-free air pump and a pure oxygen output pipe are connected with a triple valve, an output end of which is connected with a filtering tower, a drying tower, a flow meter and the ozone generator in sequence. The ozone aging testing case device is characterized in that the testing shelf takes a shape of a polygonous prism.

Description

Ozone aging experiment box apparatus

(1) technical field

The present invention relates to the environmental test equipment technical field, be specially ozone aging experiment box apparatus.

(2) background technology

Ozone content in atmosphere but be the principal element of rubber be full of cracks, and rubber is more and more wider in the utilization of every profession and trade, particularly seems particularly important in automobile industry seldom.Rubber can be subjected to the effect of ozone and wear out in the ozone media environment, make rubber surface generation ozone-induced cracking, cause performance to become bad, utilize the conditions such as ozone in manual simulation or the reinforcement atmosphere that rubbery sample is tested, can observe sample outward appearance and changes of properties.Thereby estimate the ozone resistance of rubber, ozone box is to aim at that rubber type of material carries out anti-ozone aging and the test unit that manufactures and designs, its simulation is also quickened ozone aging condition in the atmosphere, can obtain to be similar to the test findings of actual use within a short period of time.

At present, its specimen mounting of domestic ozone box is generally four prism type, and the four prism type specimen mounting can be limited in order to the sample that dress is hung, if increase sample, just must increase test stand, so just must strengthen the space of chamber, thereby cause user's acquisition cost to strengthen.

(3) summary of the invention

At the problems referred to above, the invention provides ozone aging experiment box apparatus, it is under the prerequisite that guarantees normal testing requirements, and its capacity is big, once can test the test efficiency height to a plurality of workpiece.

Its technical scheme is such: it comprises chamber, test site, air channel are set in the described chamber, described air channel is communicated with the formation circulation system with described test site, well heater, wind gage, fan and ozone generator are set in the described air channel, test stand, ozone concentration detecting device, temperature sensor are set in the test site, the bottom of described test stand connects driving structure, described fan, wind gage electricly connect by the air velocity controller, and ozone concentration detecting device and described ozone generator electricly connect by the ozone concentration controller; Temperature sensor, well heater electricly connect by temperature control equipment; The output channel of no oil gas pump and pure oxygen output channel insert T-valve, the output terminal of described T-valve be linked in sequence filtration tank, drying tower, flowmeter, ozone generator, and it is characterized in that: described test stand is polygon prismatic.

It is further characterized in that: described test stand is eight prismatic.

In the said structure of the present invention, test stand changes multi-edge column-shaped into by existing four prism type, and so relative prior art has increased several, and the sample that can install is more, under the prerequisite that does not increase customer charge, increased the test capacity like this, service efficiency is provided.

(4) description of drawings

Fig. 1 is a structural representation of the present invention;

The synoptic diagram (express the prism shape of test stand emphatically, do not express the handle at test stand top among the figure) that Fig. 2 overlooks for test stand among Fig. 1.

(5) embodiment

See Fig. 1, Fig. 2, the present invention includes chamber 1, test site 25 is set in the chamber 1, air channel 26, air channel 26 is communicated with the formation circulation system with test site 25, well heater 6 is set in the air channel 26, wind gage 8, fan 2 and ozone generator 7, test stand 22 is set in the test site 25, ozone concentration detecting device 23, temperature sensor 3, the bottom of test stand 22 connects driving structure, driving structure comprises rotating shaft 21, rotary drive motor 17, rotary speed controller 9, the drive motor 19 that moves up and down, control stretching length, the controller 20 of frequency and gear case 18.Driving structure belongs to the market prior art.Fan 2, wind gage 8 electricly connect by air velocity controller 4, and ozone concentration detecting device 23 electricly connects by ozone concentration controller 24 with ozone generator 7; Temperature sensor 3, well heater 6 electricly connect by temperature control equipment 5; The output channel of no oil gas pump 14 and pure oxygen output channel 15 inserts T-valve 13, the output terminal of T-valve 13 be linked in sequence filtration tank 12, drying tower 11, flowmeter 10, ozone generator 7, and test stand 22 is polygon prismatic.Only having expressed eight prismatic test stands 22,16 among Fig. 2 is air inlet.
